I worked with a good dev at one of my previous jobs, but one of his faults was that he was a bit scattered and would sometimes forget things.
The story goes that one day we had this massive bug on our web app and we had a large portion of our dev team trying to figure it out. We thought we narrowed down the issue to a very specific part of the code, but something weird happened. No matter how often we looked at the piece of code where we all knew the problem had to be, no one could see any problem with it. And there want anything close to explaining how we could be seeing the issue we were in production.
We spent hours going through this. It was driving everyone crazy. All of a sudden, my co-worker (one referenced above) gasps “oh shit.” And we’re all like, what’s up? He proceeds to tell us that he thinks he might have been testing a line of code on one of our prod servers and left it in there by accident and never committed it into the actual codebase. Just to explain this - we had a great deploy process at this company but every so often a dev would need to test something quickly on a prod machine so we’d allow it as long as they did it and removed it quickly. It was meant for being for a select few tasks that required a prod server and was just going to be a single line to test something. Bad practice, but was fine because everyone had been extremely careful with it.
Until this guy came along. After he said he thought he might have left a line change in the code on a prod server, we had to manually go in to 12 web servers and check. Eventually, we found the one that had the change and finally, the issue at hand made sense. We never thought for a second that the committed code in the git repo that we were looking at would be inaccurate.
Needless to say, he was never allowed to touch code on a prod server ever again.8 -
Was lead developer at a small startup, I was hiring and had a budget to add 3 new people to my team to develop a new product for the company.
Some context first and then the rant!
Candidate 1 - Amazing, a dev I worked with before who was under utilized at the previous company. Still a junior, but, she was a quick learner and eager to expand her knowledge, never an issue.
Candidate 2 - Kickass dev with back end skills and extras, he was always eager to work a bit more than what was expected. I use to send him home early to annoy him. haha!
Candidate 3 - Lets call him P.
In the interview he answers every question perfectly, he asks all the right questions and suggests some things I havent even thought of. CTO goes ahead and says we should skip the technical test and just hire the guy, his smart and knows what his talking about, I agree and we hire him. (We where a bit desperate at this stage as well.)
He comes in a week early to pick up his work laptop to get setup before he starts the next week, awesome! This guy is going to be an asset to the company, cant wait to have him join the team - The CTO at this stage is getting ready to leave the company and I will be taking over the division and need someone to take over lead position, he seems like the guys to do it.
The guys starts the next week, he comes in and the laptop we gave him is now a local server for testing and he will be working off his own laptop, no issue, we are small so needed a testing stack, but wasnt really needed since we had procedures in place for this already.
Here is where everything goes wrong!!! First day goes great... Next day he gets in early 6:30am (Nice! NO!), he absolutely smells, no stinks, of weed, not a light smell, the entire fucking office smells of weed! (I have no problem with weed, just dont make it my problem to deal with). I get called by boss and told to sort this out people are complaining! I drive to office and have a meeting with him, he says its all good he understands. (This was Friday).
Monday comes around - Get a call from Boss at 7:30am. Whole office smells like weed, please talk to P again, this cannot happen again. I drive to office again, and he again says it wont happen again, he has some issues with back pain and the weed helps.
Tuesday - Same fucking thing! And now he doesnt want to sign for the laptop("server") that was given to him, and has moved to code in the boardroom, WHERE OUR FUCKING CLIENTS WILL BE VIEWING A DEMO THAT DAY OF THE PRODUCT!! Now that whole room smells like weed, FML!
Wednesday - We send P a formal letter that he is under probation, P calls me to have a meeting. In the meeting he blames me for not understanding "new age" medicine, I ask for his doctors prescription and ask why he didnt tell me this in the interview so I could make arrangements, we dont care if you are stoned, just do good work and be considerate to your co-workers. P cant provide these and keeps ranting, I suggest he takes pain killers, he has none of it only "new age" medicine for him.
Thursday - I ask him to rather "work" from home till we can get this sorted, he comes in for code reviews for 2 weeks. I can clearly see he has no idea how the system works but is trying, I thought I will dive deeper and look at all of his code. Its a mess, nothing makes sense and 50% of it is hard coded (We are building a decentralized API for huge data sets so this makes no sense).
Friday - In code review I confront him about this, he has excuses for everything, I start asking him harder questions about the project and to explain what we are building - he goes quiet and quits on the spot with a shitty apology.
From what I could make out he was really smart when it came to theory but interpreting the theory to actual practice wasnt possible for him, probably would have been easier if he wasnt high all the time.
I hate interview code tests, but learned a valuable lesson that day! Always test for some code knowledge as well even if you hate doing it, ask the right questions and be careful who you hire! You can only bullshit for so long in coding before someone figures out that you are a fraud.16 -
Senior: Why did you refactor those ten files?
Junior: There was a method copy-pasted in every one of them, so I moved it to a utils class.
Senior: Don't you know we will have to test all of those changed classes again? Please, rollback!
Junior: ok.
... two days later ...
Senior: Why did you just copy-paste that method? Don't you know it's bad practice?10 -
Worst bad practice..
Manager: I need code today
Developer (thinking) : let me give it without unit test. Anyways tester will test it.
Manager to tester: complete testing fast.
Tester(thinking): developer must have unit tested it. Let me skip it.
Enjoy testing completed.
God help clients.. 😊5 -
HOW TO KILL A DEVELOPER
Coworker: Hey, is http://website down for you?
Me: yeah. What's up?
Coworker: Ah, that explains why my tests are failing.
Me, internally fuming: It would be good test practice to not depend directly on external services.
Coworker: I know, but this is easier.
This makes my blood boil. I'm not a huge fan of mocking and stubbing everything, but when it's actually very easy to mock something and you're too lazy, that makes me fucking angry.
Remember kids: doing it right takes longer than doing it wrong. But doing it wrong will eventually take significantly more of your time. Just wait until your shitty assumptions fail and you don't have any recourse.6 -
Paranoid Developers - It's a long one
Backstory: I was a freelance web developer when I managed to land a place on a cyber security program with who I consider to be the world leaders in the field (details deliberately withheld; who's paranoid now?). Other than the basic security practices of web dev, my experience with Cyber was limited to the OU introduction course, so I was wholly unprepared for the level of, occasionally hysterical, paranoia that my fellow cohort seemed to perpetually live in. The following is a collection of stories from several of these people, because if I only wrote about one they would accuse me of providing too much data allowing an attacker to aggregate and steal their identity. They do use devrant so if you're reading this, know that I love you and that something is wrong with you.
That time when...
He wrote a social media network with end-to-end encryption before it was cool.
He wrote custom 64kb encryption for his academic HDD.
He removed the 3 HDD from his desktop and stored them in a safe, whenever he left the house.
He set up a pfsense virtualbox with a firewall policy to block the port the student monitoring software used (effectively rendering it useless and definitely in breach of the IT policy).
He used only hashes of passwords as passwords (which isn't actually good).
He kept a drill on the desk ready to destroy his HDD at a moments notice.
He started developing a device to drill through his HDD when he pushed a button. May or may not have finished it.
He set up a new email account for each individual online service.
He hosted a website from his own home server so he didn't have to host the files elsewhere (which is just awful for home network security).
He unplugged the home router and began scanning his devices and manually searching through the process list when his music stopped playing on the laptop several times (turns out he had a wobbly spacebar and the shaking washing machine provided enough jittering for a button press).
He brought his own privacy screen to work (remember, this is a security place, with like background checks and all sorts).
He gave his C programming coursework (a simple messaging program) 2048 bit encryption, which was not required.
He wrote a custom encryption for his other C programming coursework as well as writing out the enigma encryption because there was no library, again not required.
He bought a burner phone to visit the capital city.
He bought a burner phone whenever he left his hometown come to think of it.
He bought a smartphone online, wiped it and installed new firmware (it was Chinese; I'm not saying anything about the Chinese, you're the one thinking it).
He bought a smartphone and installed Kali Linux NetHunter so he could test WiFi networks he connected to before using them on his personal device.
(You might be noticing it's all he's. Maybe it is, maybe it isn't).
He ate a sim card.
He brought a balaclava to pentesting training (it was pretty meme).
He printed out his source code as a manual read-only method.
He made a rule on his academic email to block incoming mail from the academic body (to be fair this is a good spam policy).
He withdraws money from a different cashpoint everytime to avoid patterns in his behaviour (the irony).
He reported someone for hacking the centre's network when they built their own website for practice using XAMMP.
I'm going to stop there. I could tell you so many more stories about these guys, some about them being paranoid and some about the stupid antics Cyber Security and Information Assurance students get up to. Well done for making it this far. Hope you enjoyed it.26 -
I’m back for a fucking rant.
My previous post I was happy, I’ve had an interview today and I felt the interviewer acted with integrity and made the role seem worthwhile. Fuck it, here’s the link:
https://www.devrant.io/rants/889363
So, since then; the recruiter got in touch: “smashed it son, sending the tech demo your way, if you can get it done this evening that would be amazing”
Obviously I said based on the exact brief I think that’s possible, I’ll take a look and let them know if it isn’t.
Having done loads of these, I know I can usually knock them out and impress in an evening with no trouble.
Here’s where shit gets fucked up; i opened the brief.
I was met with a brief for an MVP using best practice patterns and flexing every muscle with the tech available...
Then I see the requirements, these fucking dicks are after 10 functional requirements averaging an hour a piece.
+TDD so * 1.25,
+DI and dependency inversion principle * 1.1
+CI setup (1h on this platform)
+One ill requirement to use a stored proc in SQL server to return a view (1h)
+UX/UI design consideration using an old tech (1-2h)
+unobtrusive jquery form post validation (2h)
+AES-256 encryption in the db... add 2h for proper testing.
These cunts want me to knock 15-20h of Work into their interview tech demo.
I’ve done a lot of these recently, all of them topped out at 3h max.
The job is middling: average package, old tech, not the most exciting or decent work.
The interviewer alluded to his lead being a bit of a dick; one of those “the code comes first” devs.
Here’s where shit gets realer:
They’ve included mock ups in the tech demo brief’s zip... I looked at them to confirm I wasn’t over estimating the job... I wasn’t.
Then I looked at the other files in the fucking zip.
I found 3 of the images they wanted to use were copyright withheld... there’s no way these guys have the right to distribute these.
Then I look in the font folder, it’s a single ttf, downloaded from fucking DA Font... it was published less than 2mo ago, the license file had been removed: free for Personal, anything else; contact me.
There’s no way these guys have any rights to this font, and I’ve never seen a font redistributed legally without it’s accompanying licence files.
This fucking company is constantly talking about its ethical behaviours.
Given that I know what I’m doing; I know it would have taken less time to find free-for-commercial images and use a google font... this sloppy bullshit is beyond me.
Anyway, I said I’d get back to the recruiter, he wasn’t to know and he’s a good guy. I let him know I’d complete the tech demo over the weekend, he’s looked after me and I don’t want him having trouble with his client...
I’ll substitute the copyright fuckery with images I have a license for because there’s no way I’m pushing copyright stolen material to a public github repo.
I’ll also be substituting the topic and leaving a few js bombs in there to ensure they don’t just steal my shit.
Here’s my hypotheses, anyone with any more would be greatly welcomed...
1: the lead dev is just a stuck up arsehole, with no real care for his work and a relaxed view on stealing other people’s.
2: they are looking for 15-20h free work on an MVP they can modify and take to market
3: they are looking for people to turn down this job so they can support someone’s fucking visa.
In any case, it’s a shit show and I’ll just be seeing this as box checking and interview practice...
Arguments for 1: the head told me about his lead’s problems within 20mn of the interview.
2: he said his biggest problem was getting products out quickly enough.
3: the recruiter told me they’d been “picky”, and they’re making themselves people who can’t be worked for.
I’m going to knock out the demo, keep it private and protect my work well. It’s going to smash their tits off because I’m a fucking great developer... I’ll make sure I get the offer to keep the recruiter looked after.
Then fuck those guys, I’m fucking livid.
After a wonderful interview experience and a nice introduction to the company I’ve been completely put off...
So here’s the update: if you’re interviewing for a shitty middle level dev position, amongst difficult people, on an out of date stack... you need people to want you, don’t fuck them off.
If they want my time to rush out MVPs, they can pay my day rate.
Fuuuuuuuuck... I typed this out whilst listening to the podcast, I’m glad I’m not the only one dealing with shit.
Oh also; I had a lovely discriminatory as fuck application, personality test and disability request email sent to me from a company that seems like it’s still in the 90s. Fuck those guys too, I reported them to the relevant authorities and hope they’re made to look at how morally reprehensible their recruitment process is. The law is you don’t ask if the job can be done by anyone.6 -
Fml... you keep getting the weekly discussions right on point.
I started with the last guys right out of university... just out of Hospital.
With a brand new degree and a Crohn’s diagnosis I stepped into the first place I found hiring. They were good guys, after a junior dev... to get stuck in their muck.
I did! I nailed project after project, tricky development after tricky development. I spent 5 years with them and over those years things changed.
They had a mass cull... the original idea was to get rid of the useless middle managers, the ones managing other managers being managed by another manager for no real reason.... the ones that do fuck all with their day.
But the fucking idiots upstairs put the job of working out the cull in the shitty middle managers hands.
So, instead, they cut the titles senior, junior and everything in between. Everyone was just a thing, no senior things, no junior things. Just things.
Once they’d done that they said “we’ll we have this many things, they’re all the same, let’s get rid of the things with the highest pay checks because the other things can do it just as well for less money”...
And that’s how they cut 50% of their senior techs.
I was one of the ones left behind but the damage became obvious quick. The middle managers barked out orders at people who couldn’t complete them, and everything went to shit.
My team was rebranded twice in as many years... an obvious ploy for funding, but the cost of the team fluctuated like hell because contractors had to fill the senior positions at 3 times the cost.
Then the managers started barking out Self contradictory orders. Do this, but this way...
This would work, but not that way... try explaining that to a group of non-technical, useless as fuck middle managers. It took months, and shit flows downstream so we got the bulk of the hassle for it.
Then my boy Morpheus, got a warning... they threatened his contract for saying “this will work, but not that way”.
He kept the contract, and the manager giving him the warning said he didn’t think he should... but he, and all the middle fuckwits don’t have the balls to stand up against nonsense.
That was the breaking point for me, I handed in my notice and told them a month was what they could have.
I didn’t have a position or an idea of where to go, a few long-standing offers as back up in a pinch but not the perfect job.
On the Thursday I decided I was done, I let my manager know. Then I boshed the fuck out of my CV and updated my profiles.
My phone started ringing off the hook, a senior NG2/MEAN/Ionic dev on the market is like candy to recruiters. They’re lovely too.
I went to a few interviews that were okay but not great. Then a company got in touch... one that I immediately recognised as an IT book publisher. They said they were looking for NG/NG2 devs, senior. winner! Set up the interview.
So I’d spent the weekend with the missus, about an hour away from mine and 2 from the interview. I hadn’t planned on staying there but at 6ish she looked over at me and said “do you have to go” <- imagine that with puppy dog eyes from a gorgeous Slovenian lass.
I folded quicker than a shitty pancake toss.
We spent the night together but that meant I had to be up at 6, to go back to mine, iron my interview clothes and make it to the train to manage the interview. Fuck. I did it, but I was at the interview wired on caffeine and struggling to be awake and coherent. I still managed, that’s what I do, I make do and try to do well regardless of the situation.
That comes from being ill btw, when you’re dealt a shitty hand you learn to play it well.
They were good guys, the heads all knew what they were on about, not the middle management bs I was used to.
They demoed me live with an ng1 test, which was awesome as hell to play with.
We chatted, friendly and cool guys! I loved the place.
The end of the week they got me in for second round. Ng2 and competence test, again I went for it!
Positive feedback and a “we’ll get back to you ASAP, should be by Tuesday”...
Tuesday was the Tuesday before the Friday I was due to leave the old company... I was cutting it close.
On the Monday the offers started rolling in, a few C# ASP MVC positions, cool but I was holding out for the guys I’d interviewed with.
Then Tuesday comes around, I’m nervous as fuck but it’s okay because I knew regardless I can pay the rent in December with one of the offers.
Then said yes!
The thing that seemed most important in the process was my ability to talk to any fucker. If you’re coming up to interview, talk to everyone, the grocer, your barista, the binmen, anyone. Practice that skill above all others.
I start tomorrow morning! I can’t wait.
Final thought: middle managers are taints.7 -
Just received a test for a job I'm interviewing for. I was interviewing for a C++ position. Practice test: Create an REST API using SpringBoot, Spring Data, document with Swagger and implement continuous integration testing.
To be fair, I also mentioned I'm fluent in Java. But I've never touched SpringBoot or done any backend webdev, since my intention was to never get near it.
Deadline: Sunday. Game on...4 -
Discovered pro tip of my life :
Never trust your code
Achievements unlocked :
Successfully running C++ GPU accelerated offscreen rendering engine with texture loading code having faulty validation bug over a year on production for more than 1.5M daily Android active users without any issues.
History : Recently I was writing a new rendering engineering that uses our GPU pipeline engine.. and our prototype android app benchmark test always fails with black rendering frame detection assertion.
Practice:
Spend more than a month to debug a GPU pipeline system based on directed acyclic graph based rendering algorithm.
New abilities added :
Able to debug OpenGL ES code on Android using print statement placed in source code using binary search.
But why?
I was aware of the issue over a month and just ignored it thinking it's a driver bug in my android device.. but when the api was used by one of Android dev, he reported the same issue. In the same day at night 2:59AM ....
Satan came to me and told me that " ok listen man, here is what I am gonna do with you today, your new code will be going production in a week, and the renderer will give you just one black frame after random time, and after today 3AM, your code will not show GL Errors if you debug or trace. Buhahahaha ahhaha haahha..... Puffff"
And he was gone..
Thanks satan for not killing me.. I will not trust stable production code anymore enevn though every line is documented and peer reviewed. -
I was checking out this wk139 rants & thinking to myself how does one have a dev enemy.. o.O Well TIL that maaaaybe I have one too..
Not sure if ex coworker was a bit 'weird & unskillful' or wanted to intentionally harm us and thank god failed miserably..
I decided to finally cleanup his workspace today: he had a bad habit of having almost all files in solution checked out to himself, most of them containing no changes whatsoever... I reminded him on many occasions that this is bad practice & to only have checked out files he was currently working on. And never checkin files without changes.. Ofc didn't listen.. managed to checkin over 100 files one time, most of which had no changes & some even had alerts for debugging in them.. which ofc made it to the client server.. :/
On one or two occasions I already logged in and wanted to check if files have any real changes that I'd actually want to keep, but gave up after 40 or so files in a batch that were either same or full of sh..
Anyhow today I decided I will discard everything, as the codebase changed a lot since he left an I know I already fixed a lot of his tasks.. I logged in, did the undo pending changes and then proceed to open source control explorer.
While I was cleaning up his workspace, I figured I could test what will happen if I request changeset xy and shelveset yy, will it be ok, or do I have to modify something else & merge code.. Figured using his workspace that was already set up for testing would be easier, faster & less 'stressful' than creating another one on my computer, change IIS settings and all just, to test this merge..
Boy was I wrong.. upon opening source control explorer, I was greeted by a lot of little red Xes staring back at me... more than half the folders on TFS were marked for deletion.. o.O
Now I'm not sure if he wanted to fuck me up when he left or was just 'stupid' when it comes to TFS. O.O
So...maybe I do have a dev enemy after all.. or I don't.. Can't decide.. all I know for sure is tomorrow I'm creating another workspace to test this and I'm not touching his computer ever again.. O.O -
i honestly hate the ap computer science principles curriculum. we're taking an ap test soon, so for the past few weeks, we've been constantly taking practice tests.
it pisses me off so much. the questions, the criteria, it's all bs.
we have questions like "what will reduce the digital divide?" with choices like "education for low income families on computers." like, I DONT FUCKING KNOW.
frankly, I DONT FUCKING CARE. giving electronics to people who cant afford it is great and all, BUT IT DOESNT INVOLVE ANYTHING ABOUT COMPUTING.
HEY, COLLEGE BOARD, KNOWING IF AN ALGORITHM IS TECHNICALLY AN "ABSTRACTION" DOESNT FUCKING MATTER. WHAT MATTERS IS THAT I CAN IDENTIFY WHATS MORE EFFICIENT, WHERE A BUG IS, CONCEPTS INVOLVED IN PROGRAMS, THINGS LIKE THAT.
NOT IF DNS IS SIMILAR IN STRUCTURE TO THE US POSTAL SYSTEM.
god i hope whoever wrote this gets hit in the head by a github server that was dropped from the 2^8th floor.2 -
I opened an issue on a repo telling the owner that placing a "test passing" badge on the readme but not having other tests than an "ExampleTest" and no tests of the actual functionality is bad practice and what he thinks about updating the readme.
The result was a deletion (not close) of the issue and a ban from contributing (issues, PRs) on any of his projects.
And it was not some small "ten persons use this" project but a large boilerplate project with 2.4k github stars and over 800 forks. You would expect a little bit more professionalism of someone with that popularity.4 -
I wanna be a millionaire, so fuckin bad.
So, throughout this week there have been massive trials and tribulations regarding my lack of coding practice however through many nights and days coding I have almost completed the task I was set last week.
I didn't realise how out of practice I was so this posed as a big challenge for me. However I pulled through and tomorrow it will be ready to send for the interview!
I also have another test to do in vanilla php - Typical blog which would be such a doddle now I'm back in the zone. I just have to remember I'm not using Laravel!
The sense of accomplishment is real and I'm so relieved I've come this far. Maybe I will have this career of my dreams which I rightfully deserve.
Below is Stripe, doing random tests :) -
Next year I will strive to achieve the best test coverage on all our components and design all our new features using best-practice agile methodology with a realtime user involvement.
Reverend on 7 January: Fuck that, we need to ship this shit to production now. -
So technical interview today but woke up (6am) and started thinking about it and it led to this rant about algorithms. This is probably going into a Medium post if I ever get around to finishing it but sort of just wanted to share the rant that literally just went off in my mind.
*The problem with Algorithms Technical Interviews Is They don't test Real skills*
Real world problems are complex and often cross domain combining experience in multiple areas. Often the best way is not obvious unless you're a polymath and familiar with different areas, paradigms, designs. And intuitively can understand, reason, and combine them.
I don't think this is something a specific algorithm problem is designed to show. And the problem is the optimal solution to some of these and to algorithm design itself is that unless you train for it or are an algorithm designer (practice and experience), you can only brute force it in the amount of time given.
And quite frankly the algorithms I think we rely on daily weren't thought of in 30 minutes. The designers did this stuff for a living, thought about these problems for days and several iterations… at least. A lot were mathematicians. The matrix algorithm that had a Big O of 7N required a flash of insight that only someone constantly looking and thinking about the equations could see.
TBA
-system design
-clean readable coding practices
...
TLDR: I could probably go on and on about this stuff for hours jumping from item/example/area to the next and back again... But I don't think you can test these (~20) years of experience in a 1 hr technical interview focused on algorithms...8 -
Todays story: conversation between me and my brain about a app that i have planned for a long while.
The application is just a huge, specyfic json editor/manager for a game that i like. The game uses json files to determine unit charactetistics. So in order to make modding easier i want to make a tool for that that is fancier and easier to use than a notepad.
Brain> Lets make a app that allows you to mod the game easier!
Me> Good idea. How would you want to make it?
Brain> Lets use C# cause you main that lang currently and you have experience with json parser lib.
Me> That is true. So what do you wanna implement first?
Brain> Oh. I have thought about it before! I want to implement: (10 000 features) and maybe few more later!
Me> It sounds like a infinity project, shouldnt you implement like 1 or 2 features at first and then jump to other ones?
Brain> Yes... but i dont wanna refactor those features latter so let just implement them all at once!
Me> Dammit brain! Let just implement just one feature now! Like a simple json editor. You can use inhieritance to reuse the code later.
Brain> Ok...
* Starts with that one feature but one day later starts coding 6 more *
* Cant publish the app yet, the code looks like shit, gui is unfinished because brain wanted only to test those 6 unfinished features without propely implementing them *
Me> Brain WTF! You said that you are going to focus on one feature at the time!
Brain> I got carried a bit...
Me> ...
Me> Ok. I understand. Let just refactor the code and clean the project out of those unfinished features.
Brain> No. I have a depression now...
Me> FUCK.
* 2 month passes by without any progress on ANY of my projects*
current day
Brain> I still have depression...
Me> Ok i dont care about that anymore! Tell me something that i dont know!
Brain> Oh I have good news as well!
Me> ???
Brain> What about the home server that is going to store all mods made by the users so they can share it? It would be a good practice with networking!
Me> * Gives up *1 -
"Real devs test in production", in practice.
This was actually the second such notification I received. Not sure if this is standard for mobile app testing...2 -
300 global variables.. THREE HUNDRED FUCKING GLOBAL VARIABLES?
Are you for real?
Now let me check the line numbers again..
hmm.. line 97 to .. yep line 410, just a few new lines to seperate some of them or.. group? Idk, I've given up on trying to understand those.
Now you may ask "But ThatPerlDeb, where did you see this and what was the intention?"
Low and behold, take a chair and I may explain this to you.
First of all: Fuck the dev that wrote this!
Second: Fuck all the devs that kept up with this practice or whatever you want to fucking call this!
Now, the application is our POS system that our customers can use for a monthly fee (That this piece of garbage even requires payment is disgusting) but anyway..
The global variables sometimes are declared for labels, sometimes for some frames, sometimes just for random values to be there.
We're using Perl for the POS system and Perl ain't the best at OOP, so in the dev's defense I can understand why you'd use a few global variables, but not fucking 300!! FUCK OFF WITH THIS BULLSHIT!!
So now I'm going through this torture slowly but surely deleting globals and putting them into some sort of scope and always MANUALLY test if something broke. Again, this company sucks ass and there's nothing that could even be considered a "unit test" or something like that, so fuck that, too.
After two hours I've brought down the count of global variables to about 260, so there's progress being made..
But then, there comes more!
"But how???" you may ask, and you're right, I've asked that myself.
Now to resolve the global stuff in each file some of the initial globals are used, we got about 20-30 files which do different stuff, all fair and square, at least there was an attempt at seperating functions but god this mess is so fucking fucked up. So in order to "safely" delete a global variable I have to check if any of the variables are used in another file, and if so, in which scope and how they are used.
Spaghetti would be a compliment for this fucking disgusting piece of utter bullshit.
Let alone the code quality of this "code"
Indendation? Dafuq is dat?
Scope? Nah, we got everything global anyway
Function size? Well, some are 5 lines, some are 900 lines, who cares anyways, right?
I'm so fucking glad once I leave this shithole, for real.6 -
# Retrospective as Backend engineer
Once upon a time, I was rejected by a startup who tries to snag me from another company that I was working with.
They are looking for Senior / Supervisor level backend engineer and my profile looks like a fit for them.
So they contacted me, arranged a technical test, system design test, and interview with their lead backend engineer who also happens to be co-founder of the startup.
## The Interview
As usual, they asked me what are my contribution to previous workplace.
I answered them with achievements that I think are the best for each company that I worked with, and how to technologically achieve them.
One of it includes designing and implementing a `CQRS+ES` system in the backend.
With complete capability of what I `brag` as `Time Machine` through replaying event.
## The Rejection
And of course I was rejected by the startup, maybe specifically by the co-founder. As I asked around on the reason of rejection from an insider.
They insisted I am a guy who overengineer thing that are not needed, by doing `CQRS+ES`, and only suitable for RND, non-production stuffs.
Nobody needs that kind of `Time Machine`.
## Ironically
After switching jobs (to another company), becoming fullstack developer, learning about react and redux.
I can reflect back on this past experience and say this:
The same company that says `CQRS+ES` is an over engineering, also uses `React+Redux`.
Never did they realize the concept behind `React+Redux` is very similar to `CQRS+ES`.
- Separation of concern
- CQRS: `Command` is separated from `Query`
- Redux: Side effect / `Action` in `Thunk` separated from the presentation
- Managing State of Application
- ES: Through sequence of `Event` produced by `Command`
- Redux: Through action data produced / dispatched by `Action`
- Replayability
- ES: Through replaying `Event` into the `Applier`
- Redux: Through replay `Action` which trigger dispatch to `Reducer`
---
The same company that says `CQRS` is an over engineering also uses `ElasticSearch+MySQL`.
Never did they realize they are separating `WRITE` database into `MySQL` as their `Single Source Of Truth`, and `READ` database into `ElasticSearch` is also inline with `CQRS` principle.
## Value as Backend Engineer
It's a sad days as Backend Engineer these days. At least in the country I live in.
Seems like being a backend engineer is often under-appreciated.
Company (or people) seems to think of backend engineer is the guy who ONLY makes `CRUD` API endpoint to database.
- I've heard from Fullstack engineer who comes from React background complains about Backend engineers have it easy by only doing CRUD without having to worry about application.
- The same guy fails when given task in Backend to make a simple round-robin ticketing system.
- I've seen company who only hires Fullstack engineer with strong Frontend experience, fails to have basic understanding of how SQL Transaction and Connection Pool works.
- I've seen company Fullstack engineer relies on ORM to do super complex query instead of writing proper SQL, and prefer to translate SQL into ORM query language.
- I've seen company Fullstack engineer with strong React background brags about Uncle Bob clean code but fail to know on how to do basic dependency injection.
- I've heard company who made webapp criticize my way of handling `session` through http secure cookie. Saying it's a bad practice and better to use local storage. Despite my argument of `secure` in the cookie and ability to control cookie via backend.18 -
It is the time for the proper long personal rant.
Im a fresh student, i started few months ago and the life is going as predicted: badly or even worse...
Before the university i had similar problems but i had them under control (i was able to cope with them and with some dose of "luck" i graduated from high school and managed to get into uni). I thought by leaving the town and starting over i would change myself and give myself a boost to keep going. But things turned out as expected. Currently i waste time everyday playing pc games or if im too stressed to play, i watch yt videos. Few years ago i thought i was addicted, im not. It might be a effect of something greater. I have plans, for countess inventions, projects, personal, for university and others and ALL of them are frozen, stopped, non existant. No motivation. I had few moments when i was motivated but it was short, hours or only minutes. Long term goals dont give me any motivation. They give as much short lived joy, happines as goals in games and other things... (no substance abuse problems, dont worry). I just dont see point of my projects anymore. Im sure that my projects are the only thing that will give me experience and teach me something but... i passed the magic barrier of univercity, all my projects are becoming less and less impressive... TV and other sources show people, briliant people, students, even children that were more succesful than me
if they are better than me why do i even bother? companies care more for them, especialy the prestigious ones, they have all the fame, money, funding, help, gear without question!
of course they hardworked for ther positions, they could had better beggining or worse but only hard work matters right?
As i said. None of my work matters, i worked hard for my whole life, studing, crafting, understanding: programming, multiple launguages, enviorements, proper and most effcient algorithms, electronic circuits, mechanical contraptions. I have knowlege about nearly every machine and i would be able to create nearly everything with just access to those tools and few days worth of practice. (im sort of omnibus, know everything) But because had lived in a small town i didnt have any chances of getting the right equpment. All of my electronical projects are crap. Mechanical projects are made out of scrap. Even when i was in high school, nobody was impressed or if they were they couldnt help me.
Now im at university. My projects are stagnant, mostly because of my mental problems. Even my lifestyle took a big hit. I neglect a lot of things i shouldnt. Of course greg, you should go out with friends! You cant dedicate 100% of your life to science!
I fucking tried. All of them are busy or there are other things that prevent that... So no friends for me. I even tried doing something togheter! Nope, same reasons or in most cases they dont even do anything...
Science clubs? Mostly formal, nobody has time, tools are limited unless you designed you thing before... (i want to learn!, i dont have time to design!), and in addition to that i have to make a recrutment project... => lack of motivation to do shit.
The biggest obstacle is money. Parts require money, you can make your parts but tools are money too. I have enough to live in decent apartment and cook decently as well but not enough to buy shit for projects. (some of them require a lot or knowlege... and nobody is willing to give me the second thing). Ok i found a decent job oppurtunity. C# corporation, very nice location, perfect for me because i have a lot of time, not only i can practice but i can earn for stuff. I have a CV or resume just waiting for my friend to give me the email (long story, we have been to that corp because they had open days and only he has the email to the guy, just a easier way)
But there are issiues with it as well so it is not that easy.
If nobody have noticed im dedicated to the science. Basicly 100% scientist that want to make a world a better place.
I messaged a uni specialist so i hope he will be able to help me.
For long time i have thought that i was normal, parent were neglecting my mental health and i had some situations that didnt have good infuence on me as well. I might have some issiues with my brain as well, 96% of aspargers symptoms match, with other links included. I dont want to say i have it but it is a exciuse for a test. In addition to that i cant CANT stop thinking, i even tried not thinking for few minutes, nope i had to think about something everytime. On top of that my biological timer is flipped. I go to sleep at 5 am and wake up at 5pm (when i dont have lectures).
I prefer working at night, at that time my brain at least works normaly but i dont want to disrupt roommates...
And at the day my brain starts the usual, depression, lack of motivation, other bullshit thing.
I might add something later, that is all for now. -
API response.
For a week been working with my project manager remotely.
Then yester night had a tough one.
Me:Please send me the API endpoint so that can test it and see the response.
Him:On my side all is set just consume the response.
Me:As a practice I did first test the API using postman and the response was okay.
Me:As I had already prepared my Retrofit code to consume and parse the response I head to it.
Me:Fast forward 20 minutes into the application I realise getting some unexpected errors thanks to the guy who didn't follow my response format.
Me:I call him asking him to check how he formatted the response .
Him:He claims he formatted it as requested .
Me: Double check my work and am damn right and now raise my voice as I talk to him again and requests him to send me a screenshot of his response and I send mine.
From the screenshots turns out his response is okay as he is working from a damn localhost and my response was coming from the live server.
Feel like strangling him for wasting my previous 30 minutes2 -
Fucking fuck sonarcloud and everything about it. Part of the build pipeline for us to deploy code is to ensure that 90% of the code is covered by a unit test. Great in theory, horrible in practice. You think you've written enough tests that actually add value and test a valid piece of functionality but NO, sonarcloud throws a fucking fit because you're at 89.888 then your branch is going nowhere. Because everyone else gets to this stage and writes just enough tests to get the coverage to 90.01% then it becomes a stand off of who will break first; the code coverage threshold or your mental state.4

TAP - The Art Project.
Started in my college, been working on it for nearly a decade now and during the pandemic I was able to find co-founders and we built an amazing MVP.
But now I got busy with my new job, which is super fun, tech guy got married lol and design guy is little lost.
But over the years, experimenting with people, ideas, and everything around, my idea evolved into something which is loved by everyone I shared it and I can see a huge potential in it.
But meh! Fuck it. Because I am too bored and would rather order a practice pad and start learning to play drums (my childhood dreams), attend more gigs, and live a happier life.
Because the heart wants what the heart wants :)
For the curious ones, you can test the MVP at https://www.tap.prismo.net
And there are few other side projects that I completed which can be found on my portfolio page
https://www.floydimus.prismo.net
I am just wondering shall I redirect my main URL to my portfolio page or keep it pointed to TAP?7 -
During one of our 'pop-up' meetings last week.
Ralph: "The test code the developers are checking in is a mess. They don't know what they are doing."
ex.
var foo = SomeLibrary.GetFoo();
Assert.IsNotNull(foo);
Fred: "Ha ha..someone should talk to HR about our hiring practices. These people are literally driving the company backwards."
Me: "I think unit testing is complete waste of time."
- You could almost see the truck hit the wall and splatter watermelon everwhere..took Ralph and Fred a couple of seconds to respond
Fred: "Uh..unit testing is industry best practice. There is scientific evidence that prove testing reduces bugs and increases code quality"
Ralph: "Over 90% of our deployments are rolled back because of bugs. Unit testing will eliminate that."
Me: "Sorry, I disagree."
- Stepping on kittens wouldn't have gotten a worse look from Fred and Ralph
Fred: 'Pretty sure if you ask any professional developer, they'll tell you unit testing and code coverage reduces bugs.'
Me: "I'm not asking anyone else, I'm asking you. Find one failed deployment, just one, over the past 6 months that unit testing or code coverage would have prevented."
- good 3 seconds of awkward silence.
Ralph: "Well, those rollbacks are all mostly due to server mis-configurations. That's not a fair comparison."
Me: "I'm using your words. Unit tests reduces bugs and lack of good tests is the direct reason why we have so many failed deployments"
Boss: "Yea, Ralph...you and Fred kinda said that."
Fred: "No...we need to write good tests. Not this mess."
Me: "Like I said, show me one test you've written that would have prevented a rollback. Just one."
Ralph: "So, what? We do nothing?"
Me: "No, we have to stop worshiping this made up 80% code coverage idol. If not, developers are going to keep writing useless test code just to meet some percent. If we wrote device drivers or frameworks for other developers maybe, but we write CRUD apps. We execute a stored procedure or call a service. This 80% rule doesn't fit for code we write."
Fred: "If the developers took their head out of their ass.."
Me: "Hey!..uh..no, they are doing exactly what they are being told. Meet the 80% requirement, even if doesn't make sense."
Ralph: "Nobody told them to write *that* code."
Boss: "My gosh, what have you and Fred been complaining about for the past hour?"
- Ralph looks at his monitor and brilliantly changes the subject
Ralph: "Oh my f-king god...Trump said something stupid again ..."
At that point I put my headphones on went back to what I was doing. I'm pretty sure Fred and Ralph spent the rest of the day messaging back-n-forth, making fun of me or some random code I wrote 3 years ago (lots of typing and giggling). How can highly educated grown men (one has a masters in CS) get so petty and insecure?7 -
Architect: "Inline sql is just as performant as a stored procedure and since it is in code its safer and easier to maintain."
Me, inside my head: "I bet I could do the pencil trick on him from 'The Dark Knight' and it wouldn't hurt him as much as suck the world into the small hole in the front of his head since it is clearly a vacuum which was meant to destroy the earth. This is an obvious plant by the lizard people as a test to see if we could identify them. Killing him would be a..."
Architect: "I mean isn't it still a best practice."
Me, out loud and deadpan: "No, that is wrong and it was never a best practice. "
Me, inside my head: "Crisis averted."4 -
I really really hope that no one post this,a friend texted it to me and I wanted to share it because made my day.
Idk where it comes, so feel free if know where this came from to post it:
//FUN PART HERE
# Do not refactor, it is a bad practice. YOLO

So YOLO Driven Development isn’t your style? Okay, here are a few more hilarious IT methodologies to get on board with.
*The Pigeon Methodology*
Boss flies in, shits all over everything, then flies away.
*ADD (Asshole Driven Development)*
An old favourite, which outlines any team where the biggest jerk makes all the big decisions. Wisdom, process and logic are not the factory default.
*NDAD (No Developers Allowed in Decisions)*
Methodology Developers of all kinds are strictly forbidden when it comes to decisions regarding entire projects, from back end design to deadlines, because middle and top management know exactly what they want, how it should be done, and how long it will take.
*FDD (Fear Driven Development)*
The analysis paralysis that can slow an entire project down, with developments afraid to make mistakes, break the build, or cause bugs. The source of a developer’s anxiety could be attributed to a failure in sharing information, or by implicating that team members are replaceable.
*CYAE (Cover Your Ass Engineering)*
As Scott Berkun so eloquently put it, the driving force behind most individual efforts is making sure that when the shit hits the fan, you are not to blame.2 -
So, this has happened to me quite a few times
I write about 100 untested lines of code (I know, bad practice) and then go ahead to test it
As expected, the program crashes
Spend hours debugging, to no avail
And then I add a print statement to check where the code stopped, and hey presto! The code completes execution
I remove the print statement, the code gets stuck
Also, the codes don't use any low level functions that might be interfered by print statements anyhow
Till today, never understood how a print statement helps codes execute properly6 -
It was the last year of high school.
We had to submit our final CS homework, so it gets reviewed by someone from the ministry of education and grade it. (think of it as GPA or whatever that is in your country).
Now being me, I really didn’t do much during the whole year, All I did was learning more about C#, more about SQL, and learn from the OGs like thenewboston, derek banas, and of course kudvenkat. (Plus more)
The homework was a C# webform website of whatever theme you like (mostly a web store) that uses MS Access as DB and a C# web service in SOAP. (Don’t ask.)
Part 1/2:
Months have passed, and only had 2 days left to deadline, with nothing on my hand but website sketches, sample projects for ideas, and table schematics.
I went ahead and started to work on it, for 48 hours STRAIGHT.
No breaks, barely ate, family visited and I barely noticed, I was just disconnected from reality.
48 hours passed and finished the project, I was quite satisfied with my it, I followed the right standards from encrypting passwords to verifying emails to implementing SQL queries without the risk of SQL injection, while everyone else followed foot as the teacher taught with plain text passwords and… do I need to continue? You know what I mean here.
Anyway, I went ahead and was like, Ok, lets do one last test run, And proceeded into deleting an Item from my webstore (it was something similar to shopify).
I refreshed. Nothing. Blank page. Just nothing. Nothing is working, at all.
Went ahead to debug almost everywhere, nothing, I’ve gone mad, like REALLY mad and almost lose it, then an hour later of failed debugging attempts I decided to rewrite the whole project from scratch from rebuilding the db, to rewriting the client/backend code and ui, and whatever works just go with it.
Then I noticed a loop block that was going infinite.
NEVER WAIT FOR A DATABASE TO HAVE MINIMUM NUMBER OF ROWS, ALWAYS ASSUME THAT IT HAS NO VALUES. (and if your CPU is 100%, its an infinite loop, a hard lesson learned)
The issue was that I requested 4 or more items from a table, and if it was less it would just loop.
So I went ahead, fixed that and went to sleep.
Part 2/2:
The day has come, the guy from the ministry came in and started reviewing each one of the students homeworks, and of course, some of the projects crashed last minute and straight up stopped working, it's like watching people burning alive.
My turn was up, he came and sat next to me and was like:
Him: Alright make me an account with an email of asd@123.com with a password 123456
Me: … that won't work, got a real email?
Him: What do you mean?
Me: I implemented an email verification system.
Him: … ok … just show me the website.
Me: Alright as you can see here first of all I used mailgun service on a .tk domain in order to send verification emails you know like every single website does, encrypted passwords etc… As you can see this website allows you to sign up as a customer or as a merc…
Him: Good job.
He stood up and moved on.
YOU MOTHERFUCKER.
I WENT THROUGH HELL IN THE PAST 48 HOURS.
AND YOU JUST SAT THERE FOR A MINUTE AND GAVE UP ON REVIEWING MY ENTIRE MASTERPIECE? GO SWIM IN A POOL FULL OF BURNING OIL YOU COUNTLESS PIECE OF SHIT
I got 100/100 in the end, and I kinda feel like shit for going thought all that trouble for just one minute of project review, but hey at least it helped me practice common standards.2 -
Fucking unreal bro!!! I’m working on an issue and I pushed, then there was a bug, i fixed it again, another issue for the UI change, another fixed for sorting column. All that fixed I created separate branch. My boss called me and told me im stupid for creating a separate branch everytime on a simple fix, he told me that Git isnt used that way. He told me that his been doing this 30years already. So I asked isnt it the best practice to create a separate branch on every issue or if the branch has been merged? His answer is no. Fuck this guy and his 30years experience
I should’ve responded:
First of all, if we have a test suite then I would have notice that error but we dont. You dont even want to upgrade ruby and rails. We’re stuck at version 4 on rails. Second why are you merging my MR and reviewing it on IST? Why didnt you do that locally so you can address the issue before you merged? Third fuck you and your 30years
My actual response is:
Ahh yes sir, im sorry wont happen again, my bad, sorry for that mistake.
Fuck bro im mad!!!!4 -
I completed my driving test today. You're gonna want to read this whole thing about how it went.
I have attached a pic which highlights what you have to do in the car, to the pass the test.
And as if that wasn't easy enough already, my driving instructor sat beside me in the practice car where he had his own foot controls, handled it.
I swear I just sat in the driving seat with my foot doing nothing and my hands controlling the steering wheel. The test took a total of 45 seconds to complete.
I'm a little weirded out ngl.17 -
Some people may remember me posting about our rabbits a while ago.
Sadly they both passed away a few weeks back.
They were both a little over a year old and died within 4 days of each other, one on Wednesday morning and then one on the Saturday morning.
After about 1200 in emergency vets fees and another 500 for a post mortem on Spencer (who died on Saturday) we found out the vets had fucked up their vaccinations.
In the U.K. it is recommended that rabbits are vaccinated against 3 viruses Myxomatosis (Myxo), Rabbit Haemorrhagic Disease Variant 1 (RHD1), and Rabbit Haemorrhagic Disease Variant 2 (RHD2).
They got their vaccinations for Myxo and RHD1 in January, and went back two weeks later for their RHD2 vaccination.
Now it turns out, when they went back for the second vaccination they were incorrectly given the Myxo and RHD1 vaccinations again.
The lab results showed Spencer had RHD, but not which variant and it is safe to assume Frank also has RHD.
The vets were going to get another lab to test for the variant but decided not too (funny that they don’t want to confirm whether it was their fuck up that killed two otherwise perfectly healthy rabbits).
The wife and I are considering getting legal advise.
What fucks me off so much is that it wasn’t a situation where there were two possible courses of treatment, or they didn’t respond to treatment, it was just a human fucking up.
The practice manager also like to keep mentioning that vaccines aren’t 100% effective, and because they won’t test for the variant of RHD we will never know 100% whether their fuck up killed our rabbits.
I’m contemplating trying to get in touch with the lab and paying for the extra tests myself.
Due to the nature of the virus it also means we can’t get anymore rabbits for 3-4 months.3 -
So I promised a post after work last night, discussing the new factorization technique.
As before, I use a method called decon() that takes any number, like 697 for example, and first breaks it down into the respective digits and magnitudes.
697 becomes -> 600, 90, and 7.
It then factors *those* to give a decomposition matrix that looks something like the following when printed out:
offset: 3, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('2')]]
offset: 2, exp: [[Decimal('2'), Decimal('1')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('1')]]
offset: 1, exp: [[Decimal('7'), Decimal('1')]]
Each entry is a pair of numbers representing a prime base and an exponent.
Now the idea was that, in theory, at each magnitude of a product, we could actually search through the *range* of the product of these exponents.
So for offset three (600) here, we're looking at
2^3 * 3 ^ 1 * 5 ^ 2.
But actually we're searching
2^3 * 3 ^ 1 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
2^3 * 3 ^ 1 * 5 ^ 0
2^3 * 3 ^ 0 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
etc..
On the basis that whatever it generates may be the digits of another magnitude in one of our target product's factors.
And the first optimization or filter we can apply is to notice that assuming our factors pq=n,
and where p <= q, it will always be more efficient to search for the digits of p (because its under n^0.5 or the square root), than the larger factor q.
So by implication we can filter out any product of this exponent search that is greater than the square root of n.
Writing this code was a bit of a headache because I had to deal with potentially very large lists of bases and exponents, so I couldn't just use loops within loops.
Instead I resorted to writing a three state state machine that 'counted down' across these exponents, and it just works.
And now, in practice this doesn't immediately give us anything useful. And I had hoped this would at least give us *upperbounds* to start our search from, for any particular digit of a product's factors at a given magnitude. So the 12 digit (or pick a magnitude out of a hat) of an example product might give us an upperbound on the 2's exponent for that same digit in our lowest factor q of n.
It didn't work out that way. Sometimes there would be 'inversions', where the exponent of a factor on a magnitude of n, would be *lower* than the exponent of that factor on the same digit of q.
But when I started tearing into examples and generating test data I started to see certain patterns emerge, and immediately I found a way to not just pin down these inversions, but get *tight* bounds on the 2's exponents in the corresponding digit for our product's factor itself. It was like the complications I initially saw actually became a means to *tighten* the bounds.
For example, for one particular semiprime n=pq, this was some of the data:
n - offset: 6, exp: [[Decimal('2'), Decimal('5')], [Decimal('5'), Decimal('5')]]
q - offset: 6, exp: [[Decimal('2'), Decimal('6')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('5')]]
It's almost like the base 3 exponent in [n:7] gives away the presence of 3^1 in [q:6], even
though theres no subsequent presence of 3^n in [n:6] itself.
And I found this rule held each time I tested it.
Other rules, not so much, and other rules still would fail in the presence of yet other rules, almost like a giant switchboard.
I immediately realized the implications: rules had precedence, acted predictable when in isolated instances, and changed in specific instances in combination with other rules.
This was ripe for a decision tree generated through random search.
Another product n=pq, with mroe data
q(4)
offset: 4, exp: [[Decimal('2'), Decimal('4')], [Decimal('5'), Decimal('3')]]
n(4)
offset: 4, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('3')]]
Suggesting that a nontrivial base 3 exponent (**2 rather than **1) suggests the exponent on the 2 in the relevant
digit of [n], is one less than the same base 2 digital exponent at the same digit on [q]
And so it was clear from the get go that this approach held promise.
From there I discovered a bunch more rules and made some observations.
The bulk of the patterns, regardless of how large the product grows, should be present in the smaller bases (some bound of primes, say the first dozen), because the bulk of exponents for the factorization of any magnitude of a number, overwhelming lean heavily in the lower prime bases.
It was if the entire vulnerability was hiding in plain sight for four+ years, and we'd been approaching factorization all wrong from the beginning, by trying to factor a number, and all its digits at all its magnitudes, all at once, when like addition or multiplication, factorization could be done piecemeal if we knew the patterns to look for.7 -
[UPDATE]
As some 6 of you might know from my previous post I was gonna start with my OSCP course. Well, I didn't.
I thought maybe I needed some more practice before I do, and I joined this wonderful platform called HackTheBox (hackthebox.eu)
It's a really amazing place to test a lot of your skills in pentesting. You practice on various machines, each having it's own challenge different from another, it really helps in thinking differently and learning while you move forward.
I'd really like to recommend it to anyone who is interested in it! :)4 -
Had my first ever final interview as a developer after passing the first ever coding assignment, now can't stop thinking if I should have answered the questions differently.
I was very honest to my answer when they asked "How do you test your application?" As I started building the app with 0 knowledge about software development and know nothing about software testing. So I just told them the truth that I did not do any proper test, I just used a checklist and manual test to test my app and the app that I created for the assignment was the first app that I write a proper test cases and implement an automated test. The same goes to other questions like automated deployment and OOP experience. I just told them the honest truth even though I know that they are not the best practice. Did I just f*cked up the interview??
Arghh can't stop thinking2 -
Today is thursday. Oh no.
At thursdays I have a 8h30-19 schedule (I have 1h30' of free time to go home and cry after I finish a class at 15h30 though) and there's this one class I DREAD. It's a 2h class at 17h and it's an exercise class. This wouldn't be so bad it I actually understood the code behind the exercises, because they don't teach us code in the theory classes (btw it's C. I hate that language because of all this). The teacher pretty much tells us "do this exercise", waits like 10' and then starts to (try to) explain what we're supposed to do. Oh my god.
The other day he was like "write "exec ( ... "text" ... )", compile and execute". It didn't work. Of course it didn't why would it? I was switching around between terminal, manual and text editor, to no avail. In the end he explained but I don't think I got it.
Every time I think about this class I die a little inside and start to become somewhat anxious to be honest. The theory is not that that hard, the practice part is what is killing me (I have test in 2w but I'm just gonna start studying earlier so I can go watch this match LoL).
Does someone know a good book (preferably online, if possible) or a good website on C? I really need to read that, that language is killing me.
Bonus: the other day I had to do a homework that was to be delivered. We had to write a program that read the program and its arguments like this:
./program_name
numArgs
arg1
arg2
etc
I wrote the code, had some bumps in the way, asked a colleague for help because we needed to have a custom function made that was to be done in the class but that I couldn't make because of the reasons above. Then it came the time to test. My VM broke (I think I'm gonna format my PC to try to fix that. Have installed some other versions of the VM but the installations fails or the machine doesn't start) so I sent it to said colleague to test. She said it did OK and so I sent the work to this website we have to send our works to.
"2 errors".
What? What happened? She said it worked just fine.
Looked at my code, couldn't see anything wrong.
Asked the same colleague for help.
Turns out I missed a space. A SPACE. I don't think I've ever felt so frustrated in my life. A presentation error in Java is a good thing, at least we know the program works fine, it's just the output that's wrongly formatted. But C? Nope, errors all around, oh my god. I'm still mad about it.
And I owe her a chocolate.1 -
Do you guys still see the relevance of using code freezing instead of just properly managing versions, repositories and branches in a cyclical manner, given how advanced software practices and tools are supposed to be?
To give some context, the company I work for uses the complete trash project management practice of asking teams to work on a sprint basis, but there is still a quarterly milestone and code freeze to commit to and it's where shit hits the fan.
Development teams rush features at the end of the quarter because they had to commit at the very least to a 6 months in advance planning (lol?) and turns out, not being able to design and investigate properly a feature combined with inflexible timelines has high chances to fail. So in the end, features are half-assed and QA has barely any time to test it out thoroughly. Anyways, by the time QA raises some concerns about a few major bugs, it's already code freeze time. But it's cool, we will just include these bug fixes and some new features in the following patches. Some real good symver, mate!
Of course, it sure does not help that teams stopped using submodules because git is too hard apparently, so we are stuck with +10Gb piece of trash monolithic repository and it's hell to manage, especially when fuckfaces merges untested code on the main branches. I can't blame Devops for ragequitting if they do.
To me, it's just some management bullshit and the whole process, IMO, belongs to fucking trash along with a few project managers... but I could always be wrong given my limited insight.
Anyways, I just wanted to discuss this subject because so far I cannot see code freezing being anything else than an outdated waterfall practice to appease investors and high management on timelines.8 -
First and foremost, students should be carefully taught the logic and mentality behind programming. Most of the time I see that the introductory programming courses waste so much energy in teaching the language itself. So students kinda just get fucked cause many people end up ending the course without having actually gained the "programming perspective".
Stop teaching pointers and lambdas and even leave the object oriented stiff till later. If a student doesn't know why we use a For loop then how can they learn anything else.
I believe once that thing in your brain clicks about programming, everything goes smooth from there... kinda :P
Second of all, and this pertains mainly to the engineering and science disciplines.
We need a fundamental and strong mathematical foundation. And no I don't mean taking fucking double integrals. Teach us Linear Algebra, Graph theory, the properties of matrices, and Probability theory.
One of the things I suffered from most and regret in university is having a weak foundation in math and having to spend more time catching myself up to speed.
It's so annoying reading a paper on a new algorithm or method and feeling like an idiot because I can't understand what magic these people did.
Numerical Methods...
Ok this is more deeper, maybe a 2nd year course.
But this is something we take for granted.
Computers don't magically add and subtract and multiply.
They fuck up.
And it'll bite you in the ass if you're not even aware that the computer we all love so much isn't as perfect as we think
Some hardware knowledge.
Probably a basic embedded systems course with arduinos
just so you can get a feel for how our beautiful software actually makes those electrons go weeeeeeeee
And finally
Practice practice
Projects projects
like honestly
just give me the internet and some projects
Ill learn everything else
Projects are the best motivation
I hate this purely theoretical approach
where we memorize or read code and write these stupid exams
Test what we are capable off
make us do projects that take sleepless nights and litres of coffee
And judge our methods, documentation, team work, and output
Team work skills and tools (VCS, communicating, project management, etc.)
Documentation and Reporting
Properly
:)
maybe even with LaTeX :D
Yeah that's the gist of whats on my mind at the moment regarding an ideal computer science education
At least the foundations
The rest I leave it to the next dude. -
Im taking an AP class for Java at my school. (AP is like an honors class). But there is an standardized test throughout the US that everyone takes. But it's so annoying because you are not allowed computers on the test so you have to HANDWRITE all of your code. So the way we "practice" for the test is in our class is we use a buggy ass program called greenfoot which is worse than writting in notepad because it crashes every 5 mins but only on Windows computers and since I go to a school and everyone it a retarded they all have Macs so my Windows laptop is a "non issue" like wtf. So now I just use intelij and tell the teacher to fix it but our school has a code where teachers are not allowed to touch laptops so he's just stuck right now.
Forgot to mention that the reason why we use greenfoot is because there is no auto fill features not even closing brackets automatically which "makes us learn better".
Also all of our tests are hand written which is annoying.3 -
@11.30 pm -->BF: "Comm'on now...what Ya still doing there..aren t Ya comeing??? O.o already..."
ME: "Soon hun, i m learning some snake handeling here..hold on now!"
BF: "Yeeahp..Ya are handeling it all right already, you need to put it in the practice too. Come now. !" <<<--grinns.
ME: <<--lifting my glasses up to my head slowly: " I am writing...handwriting...the code!! Python!...?"
BF: "Yeah, i know...i saw yar test -B+.
If ya had done the finances calculus program for our maintance..my building checks, our food, your clothes...you would have more practice to put it into use...and you would have got an A probably..." He s freaking smirks and i went
qwaaak qwaaak qwaak- squachhh
I am so putting it into Rant )
..and i am so keeping him... -
So, I have been working for a company XYZ for about 2 years now and for this 2 years, we are just two engineers handling everything. The job is becoming super stressful and time consuming, the founders dictates how the engineering team operate, ranging from choosing a third party service we are to integrate into the platform without letting us know and also study the api to see if it will be the most viable one to use.
Imagine using a third party service that you can't get through to when something is unclear?
I and my team mate has asked the founders to hire engineers so the work load on us will reduce, they said it's on their mind ( this request was made months ago), fast forward last week, we were told to start interviewing interns ( I don't have problem with interns working with us ), but what we asked for was experience engineers working with us but the founders did entire 180 degree of what we asked.
We have been asking for a QA Engineer for months and months now, all we get is we will hire one, and till now nothing is been done.
Following good software practice has been a problem in company XYZ, we have been finding it difficult to write test and documentation (this shit makes me seriously sick and hate myt po self).
On top of all this, the salary is shitty, there are no benefits, we are coerced into working during weekends (most times), and we are also told to work during our holiday, no single health insurance.
I think I have come to that point where I will have to say good bye ( but I am finding it difficult to do this).
Any suggestions ? Should I wait until I get another job and then I resign from company XYZ or just resign.5 -
I'm starting to gain a dislike for OOP.
I think classes make it easy for me to think of the entities of a problem and translate them into code.
But when you to attempt to test classes, that's when shit hits the fan.
In my opinion, it is pointless to test classes. If you ever seen test code for a class, you'll notice that it's usually horrible and long.
The reason for this is that usually some methods depend on other methods to be called first.
This results in the usual monolithic test that calls every goddamn method on the class.
You might say "ok, break the test into smaller parts". Ok. But the result of that attempt is even worse, because you end up with several big tests cases and a lot of duplicate code, because of the dependency of some methods on others.
The real solution to this is to make the classes be just glue: they should delegate arguments onto functions that reside on its own file, and, maybe afterwards emit events if you are using events.
But they shouldn't have too much test code classes though. The test code for classes should be running a simple example flow, but never doing any assertions other than expecting no exceptions.
For the most part, you'd be relying on the unit testing that is done for each delegated function.
If you take any single function you'll see that it's extremely easy to write tests for it. In fact, you can have the test right next to the fuction, like <module>.xyz <module>.test.xyz
So I don't think classes shouldn't be used at all, they should just be glue.
As you do normal usage of this software this way, when a bug is discovered you'll notice that the fix and testing code for this bug is very usually applied to the delegated functions instead of being a problem of classes.
I think classes by themselves sound sane in paper, but in practice they turn into a huge fucking messes that become impossible to understand or test.
How can something like traditional classes not get chaotic when a single class can have x attributes and y methods. The complexity grows exponentially. And sometimes more attributes and methods are added.
Someone might say "well, it's just the nature of problems. Problems can have a lot of variables".
Yeah, but cramming all of that complexity into a single 200 lines class is insanity.12 -
I'm not experienced in VB Forms. So can someone who is, tell me if I'm just too inexperienced or if Im right about this?
Im tasked with fixing some bugs in a VB Forms project that a privious employee wrote some years ago. When I opened the project and checked it out, there was over 5600 lines of code in the codebehind for the form.
I feel like this is somewhat bad practice, no comments, no documentation... Nothing. And to top it off, among the worst naming of Subs and variables ever. Stuff like: "Run", "Stop", "Feeder", "When Load".
Oh, and the best part? The guy forgot some test code in the software, so when he left, the software stoped functioning. For real, he coded in a dependency to his own account in The AD.1 -
How to Jitter Click and Increase Clicks per Second?
If you are a gamer who wants to increase clicks per second speed, you must learn how to jitter click. Here, I am sharing an easy step-by-step process of jitter clicking and how to master the technique with practice.
For those who are new to the concept of jitter clicking, let me first tell you about that.
What is Jitter Clicking?
Jitter Clicking is an advanced mouse-clicking technique that gives you more clicks per second on the CPS test ( https://cpstest.pro ) than the regular way of clicking. You use your forearm and wrist muscles to create vibrations in the hand and use it to make more clicks in less time.
How to Jitter Click? Step by Step Guide
If you want to learn jitter clicking, follow the steps provided below.
1. First, hold the mouse properly. A claw grip works the best for jitter clicking.
2. Start by making for forearm stiff and putting all the stress on the wrist muscle.
3. Use the stressed wrist to create vibration in your hand and the index finger.
3. The index finger must be on exactly the top of the mouse button keeping it just a few millimeters away.
4. The vibration in the finger will make the mouse button click way faster than normal
That's it. You've successfully learned how to jitter click. It might seem a bit difficult in the beginning, but after you practice it enough, you'll be able to master jitter clicking within a week.
Among all my gamer friends who started using jitter clicking, most of them have seen significant improvement in their clicking speed. Those who had around 6-8 CPS earlier, started to get 11-12 CPS within a week of jitter click practice. A few of them went even beyond that with 14 clicks per second.
According to stats, jitter clicking is recommended as the fastest way of clicking.
Clearly, it is a good technique but those who are starting to jitter click should take proper precautions as the method involves unusual muscle movements and may lead to wrist pain, cramps, or even carpal tunnel syndrome.
It is advised that gamers take sufficient breaks while jitter clicking and not perform it for long time periods in one go.
Keeping this in mind, I hope you'll definitely get better clicks per second using the jitter click technique.4 -
Giving them a bit test of programming told them young man..young gal, if you wana go far with this shit you have to be serious....You cnt just wake up from ur sleep en say you wana code..Nop it takes passion and practice.

I am developing a webapp with a couple of friends and we want to implement stripe API with Django Rest. Does anybody knows about good integration test packages/practice that could be useful in this case?
